I think that line might be throwing you off some girls is all
If it is... they weren't that into me to begin with.
Usually the ones that are into me are pretty forgiving.
edit: It's really not worth the uphill battle to try and convince someone that's on the fence about me to date me.
I've tried that before and it usually results in rather lukewarm dates.
Thing is, the only way they could even remotely be """""""into you""""""" (imagine 1 solid minute of airquotes) at that stage is based on 2 pics and 5 lines, that for all they know have been cautiously crafted and refined for weeks.
So when the first thing they hear directly from you, the actual person, not the profile, could easily depending on the person come across as "yo I'm busy, s'up?' sort of stuff you'd give to someone who's half bothering you, it isn't really great. First impressions matter, and pics+bio isn't a tenth of it.
Personal opinion and all that tho, and I've never used dating sites/apps, so what do I know
